Find the equation for the circle with center (4,-5) and passing through (5,-4)

  (x -4)^2 +(y +5)^2 = 2

Step-by-step explanation:

The equation of a circle centered at (h, k) through point (p, q) is ...

  (x -h)^2 +(y -k)^2 = (p -h)^2 +(q -k)^2

Filling in your given numbers gives ...

  (x -4)^2 +(y +5)^2 = (5-4)^2 +(-4+5)^2

  (x -4)^2 +(y -5)^2 = 2

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
